“…Paradilepis phalacrocoracis Ukoli, 1968 is a species inquirenda , as the diagnosis was based upon a specimen without a scolex. On the basis of descriptions, we recognize the remaining 12 species from Schmidt's list as members of Paradilepis : P. caballeroi Rysavy & Macko, 1973 , P. delachauxi (Fuhrmann, 1909), P. diminuta Huey & Dronen, 1981 , P. kempi, P. longivaginosus, P. maleki Khalil, 1961, P. minima, P. patriciae Baer & Bona, 1960, P. rugovaginosus Freeman, 1954, P. scolecina, P. simoni Rausch, 1949, and P. urceus (Wedl, 1855). We also recognize P. urceina Bona, 1975, which was not mentioned by Schmidt.…”

“…Adult cestodes of the genus Paradilepis are almost entirely confined to pelicaniform birds, in many cases cormorants (Freeman, 1954; Mahon, 1955; Clark, 1957). Species have also been reported from other pelicaniform (spoonbills, pelicans, ibis, herons) and accipitriform (kites and osprey) hosts (Mayhew, 1925; Freeman, 1954; Mahon, 1955; Khalil, 1961; McLaughlin, 1974; Ryzhikov et al , 1985; Ortega-Olivares et al , 2008). Metacestodes of Paradilepis inhabit a wide range of fish orders as second intermediate hosts: Acipenseriformes, Antheriniformes, Cypriniformes, Esociformes, Gasterosteiformes, Perciformes, Salmoniformes, Scorpaeniformes and Siluriformes (Ching, 1982; Ryzhikov et al , 1985; Scholz & Salgado-Maldonado, 2001; Scholz et al , 2004).…”

First report of a gryporhynchid tapeworm (Cestoda: Cyclophyllidea) from New Zealand and from an eleotrid fish, described from metacestodes andin vitro-grown worms

Metacestodes are often found in the body cavity of the common bully (Gobiomorphus cotidianus McDowall), from freshwater habitats in Otago, New Zealand. Identification of metacestodes relies only on the number, size and shape of the rostellar hooks. To attempt species determination, we cultivated metacestodes in vitro for up to 23 days, during which they matured to at least the male stage of development, although female organs were not discernable. Identified as members of the genus Paradilepis Hsü, 1935 (family Gryporhynchidae), these specimens are compared to previously described species, in particular P. minima (Goss, 1940), from Australia, the closest species, both geographically and morphologically. Although the size of scolex, suckers and proglottids differ significantly from those of P. minima, we are cautious about interpreting 'adults' grown in vitro, because we are unsure whether the artificial conditions alter development. For this reason, and because of the lack of female organs, we refrain from erecting a new species, and refer to the specimens as Paradilepis cf. minima until such time as the adults are found in the definitive host. With this proviso we present here a description of the in vitro-grown worms and the metacestodes as a preliminary study of this cestode. A molecular analysis of small subunit (SSU) rDNA sequences, shows the position of P. cf. minima and another gryporhynchid, Neogryporhynchus cheilancristrotus (Wedl, 1855), to be equivocal, but confirms their exclusion from the Dilepididae and Hymenolepididae. This is the first record of a gryporhynchid from New Zealand, and the first from the fish family Eleotridae.

An annotated list of larvae (metacestodes) of gryporhynchid tapeworms (Cestoda: Cyclophyllidea) from freshwater fishes in Africa is provided with numerous new host and geographical records. Newly collected materials from Burundi, Democratic Republic of the Congo, Kenya, Madagascar, Namibia, Senegal, South Africa, Sudan and Zimbabwe practically double the total number of species reported from African fish so far. We confirm the occurrence of 16 species (five unidentified to the species level and most likely representing new taxa) belonging to the genera Amirthalingamia Bray, 1974 (1 species), Cyclustera Fuhrmann, 1901 (2 species), Dendrouterina Fuhrmann, 1912 (1 species), Neogryporhynchus Baer & Bona, 1960 (1 species), Paradilepis Hsü, 1935 (4 species), Parvitaenia Burt, 1940 (5 species), and Valipora Linton, 1927 (2 species). Additionally, metacestodes of four unidentified species of Paradilepis and Parvitaenia are reported from fish for the first time. Rostellar hooks of all species are illustrated and their measurements are provided together with a host-parasite list. The molecular phylogenetic analysis based on partial LSU rDNA sequences offers the first insight into the internal phylogenetic relationships within the family. Together with the morphological observations, the present study provides a taxonomic baseline for future studies on this largely neglected, but widely distributed and relatively frequent, group of parasites of African fishes, including economically important cichlids like tilapias and cyprinids.
